Description

AQUEOUS PREPARATIONS CONTAINING A WATER-SOLUBLE OR WATER-DISPERSIBLE COPOLYMER CONTAINING AT LEAST ONE MONOMER WITH A NITROGEN ATOMIC DESCRIPTION 5 The present invention relates to aqueous preparations containing at least one water-soluble or water-dispersible copolymer with at least one protonable monomer and at least one protonomeric further atom, with at least one proton ionic monomer, and at least one further protonating monomer and a cationonizing monomer with it, and at least one proton ionic monomer, with at least one proton ionic monomer, and at least one proton ionic monomer, with at least one proton ionic monomer, and at least one proton ionic monomer, with at least one other ionomeric proton having a cationic monomer group copolymerized copolymerized copolymer contains 10 and at least one cosmetically acceptable carrier, the pH of the aqueous preparation having a value in the range from pH 4 to pH 6.

The invention further relates to the use of these aqueous preparations and processes for their preparation. 15 Cosmetically and pharmaceutically acceptable water-soluble polymers are widely used in cosmetics and medicine. In soaps, creams and lotions, for example, they usually serve as formulating agents, e.g. as a thickener, foam stabilizer or water absorbent or also to alleviate the irritating effect of other ingredients 20 or to improve the dermal application of active ingredients.

Your task in hair cosmetics is to influence the properties of the hair. In pharmacy, for example, they serve as coating agents or binders for solid pharmaceutical forms. 25 For hair cosmetics, film-forming polymers are used, for example, as conditioners to improve dry and wet combability, feel, gloss and appearance, and to give the hair antistatic properties. It is known to use water-soluble polymers with cationic functionalities in 30 hair conditioning agents, which have a greater affinity for the structurally induced negatively charged surface of the hair and prevent electrostatic charging of the hair. The structure and mode of action of various hair treatment polymers are described in Cosmetic & Toiletries 103 (1988) 23. Commercially available cationic conditioner polymers are e.g. cationic hydroxyethyl cellulose, cationic polymers based on N-vinylpyrrolidone, e.g. Copolymers of N-vinylpyrrolidone and quaternized N-vinylimidazole or copolymers of acrylamide and diallyldimethylammonium chloride.

For example, vinyl lactam homo- and copolymers and carboxylate group-containing polymers are used to set hairstyles. Requirements for hair setting resins are, for example, strong strengthening with high air humidity, elasticity, washability from the hair, compatibility in the formulation, as low as possible ge stickiness of the film formed and a comfortable grip of the hair treated with it.

The provision of products with a complex property profile is often difficult. There is therefore a need for cosmetic preparations which are capable of forming essentially smooth, tack-free films which impart good sensor-detectable properties, such as a pleasant grip, to the hair and the skin and at the same time have a good conditioning action or setting action.

EP-A-670 333 describes crosslinked water-soluble polymer dispersions which can be obtained by polymerizing a monomer mixture comprising at least one water-soluble monomer, at least one crosslinking agent and, if appropriate, hydrophobic and / or amphiphilic monomers in the presence of a polymeric dispersant. In addition to a large number of other water-soluble monomers, N-vinylpyrrolidone and monomers with cationic / cationizable groups, such as N-vinylimidazole, can also be used.

EP-A-929 285 teaches the use of water-soluble copolymers which contain vinyl carboxamide units and vinylimidazole units in copolymerized form as a constituent of cosmetic compositions.

WO 00/27893 describes aqueous polymer dispersions based on N-vinylcarboxamides and, if appropriate, comonomers, where, in addition to a large number of others, N-vinylpyrrolidone, N-vinylimidazole and N-vinylimidazole derivatives are also mentioned. The polymerization takes place in the presence of at least one polymeric dispersant.

WO 03/92640 relates to cosmetic compositions which contain at least one water-soluble copolymer which can be obtained by radical copolymerization of acrylic acid amide and / or methacrylic acid amide and further water-soluble α, β-ethylenically unsaturated compounds which can be copolymerized therewith, optionally in the presence of a water-soluble polymeric graft base.

There is still a need for improvement in the preparations for cosmetic and pharmaceutical applications known from the prior art. This applies in particular to preparations containing polymers which, in addition to good film-forming properties, also allow the rheological properties of the products to be adjusted, so that e.g. can be formulated in the form of mousses, foams or gels.

The object of the present invention was to provide a cosmetic preparation which is particularly suitable for mousse and foam applications and has improved to find properties that are also suitable for producing elastic hairstyles with strong strengthening even at high humidity and are further characterized by good washability, the lowest possible stickiness and good grip of the treated hair.

This object is achieved by aqueous preparations containing at least one water-soluble or water-dispersible copolymer with cationogenic groups, which contains at least one monomer having at least one protonatable nitrogen atom and at least one further copolymerizable monomer copolymerized therewith, and at least one cosmetically acceptable carrier, the pH value of the aqueous preparations has a value in the range from pH 4 to pH 6.

The invention therefore relates to aqueous preparations containing

A) at least one water-soluble or water-dispersible copolymer A) with cationogenic groups, the

a) at least one monomer with at least one protonatable nitrogen atom and

b) contains at least one further copolymerizable monomer copolymerized therewith, and

B) at least one cosmetically acceptable carrier, the pH of the aqueous preparation having a value in the range from pH 4 to pH 6.

In the context of this invention, protonatable nitrogen atoms are those nitrogen atoms which can be converted into the cationic charge state by protonation, preferably with the aid of acids.

Adjustment of the pH value

The pH value is a term introduced by S0rensen for the negative decimal logarithm of the concentration of the hydrogen ions c (H ⁺ ) in mol / L in aqueous solution.

The pH value of water (neutral pH range) is 7.0 at 22 ° C. The pH value is temperature-dependent and decreases towards higher temperatures. The pH value is determined by potentiometric measurements known to the person skilled in the art using pH electrodes (glass electrodes) or colorimetrically using indicator dyes (pH paper, litmus paper, pH sticks). Examples of indicators are in Ullmann's Encyclope- dia of Industrial Chemistry, 6th edition, vol. 17, pages 645 to 655. All commercially available pH measuring devices can be used to determine the pH value with electrodes.

The pH of the preparations according to the invention is determined by a known method mentioned above to the person skilled in the art at temperatures of 20 to 25 ° C.

Accordingly, it may also be advantageous to adjust the pH values of the monomer feeds to a value in the range from pH 6 to pH 7 before or during the polymerization and to adjust the pH value of the aqueous preparation to pH after the polymerization has ended Adjust 4 to pH 6.

The invention accordingly furthermore relates to a process for the preparation of the preparation according to the invention, characterized in that the pH is adjusted to a value in the range from 4 to 6 after component A) has been prepared.

Polymerization in water or a water / alcohol mixture, for example in a water / ethanol mixture, is particularly preferred.

If water is used as a solvent component, demineralized water is preferably used.

The precipitation polymerization takes place, for example, in an ester, such as ethyl acetate or butyl acetate, as the solvent. The resulting polymer particles precipitate out of the reaction solution and can be isolated by customary methods, such as filtration using negative pressure. In the case of precipitation polymerization, polymers with higher molecular weights are generally obtained than in the case of solution polymerization.

The polymerization temperatures are preferably in a range from about 30 to 120 ° C., particularly preferably 40 to 100 ° C. The polymerization is usually carried out under atmospheric pressure, but it can also take place under reduced or elevated pressure. A suitable pressure range is between 1 and 5 bar. To prepare the polymers A), the monomers can be polymerized using initiators which form free radicals.

The peroxo and / or azo compounds customary for this purpose can be used as initiators for the radical polymerization, for example alkali metal or ammonium peroxydisulfates, diacetyl peroxide, dibenzoyl peroxide, succinyl peroxide, di-tert-butyl peroxide, tert-butyl perbenzoate, tert.- Butyl perpivalate, tert.-butylperoxy-2-ethylhexanoate, tert.-butyl permaleinate, cumene hydroperoxide, diisopropyl peroxidicarbamate, bis- (o-toluoyl) peroxide, didecanoyl peroxide, dioctanoyl peroxide, dilauroyl peroxide, tert.-butyl perobutyl, isobutyl peris tertiary amyl peroxide, tertiary

A preferred regulator is cysteine.

To achieve the purest possible polymers with a low residual monomer content, the polymerization (main polymerization) can be followed by a post-polymerization step. The post-polymerization can be carried out in the presence of the same or a different initiator system as the main polymerization. The postpolymerization is preferably carried out at least at the same temperature, if appropriate at a higher temperature than the main polymerization. If desired, the reaction mixture can be subjected to steam stripping or steam distiilation following the polymerization or between the first and the second polymerization steps.

According to the invention, the pH of the aqueous preparation can be adjusted to a value in the range from pH 4 to pH 6 before or after steam stripping or steam distillation.

If an organic solvent is used in the preparation of the polymers, this can be removed by customary processes known to the person skilled in the art, for example by distillation under reduced pressure. The polymerization is preferably carried out at a pH in the range from 6 to 9, particularly preferably from 6 to 7.5. The pH is adjusted by adding a suitable acid or by adding a suitable base.

The liquid polymer compositions obtained can be obtained by various drying methods, e.g. Spray drying, fluidized spray drying, roller drying or freeze drying can be converted into powder form. Spray drying is preferably used. The polymer dry powders obtained in this way can advantageously be converted again into an aqueous solution or dispersion by dissolving or redispersing them in water. Powdery copolymers have the advantage of better storage stability, easier transportation and generally have a lower tendency to infest germs.

Another object of the invention is to adjust the liquid polymer compositions to a pH in the range from pH 4 to pH 6 after the polymerization is complete and before drying and / or conversion into the powder form.

applications

The copolymers synthesized according to synthesis examples S1 to S11 were prepared as foam formulations (examples SF1 to SF16) in accordance with the following composition.

SF1- SF16: foam formulations:

2.00 g Luviquat ^® Mono LS

0.20 g perfume oil

2.00 g WS ^* polymer

0.10 g Euxyl ^® K 100 qs Phenonip ^® ad 100 g water dem.

10.00 g propane / butane 3.5 bar

Production: The components were weighed in and slowly homogenized at room temperature with stirring. The preparation was then filled into a suitable container and the propellant gas was added.

* WS: Active ingredient polymer stands for the mass of polymer in g in 100g of the total formulation

SF2, SF4, SF7, SF9, SF14: The pH of the foam formulations based on the polymers according to the information in Table 2 was adjusted with lactic acid to the pH given in Table 2.

SF11 and SF12 are foam formulations in which the pH of the aqueous preparation was set as foam after the polymerization was complete but before formulation.

SF16, SF18: the pH of the foam formulation based on the polymer as specified in Table 2 was adjusted to the pH given in Table 2 using phosphoric acid.

SF1, SF3, SF5, SF6, SF8, SF10, SF13 and SF15 are foam formulations in which the pH of the aqueous preparation has not been adjusted after the polymerization has ended (comparative examples). Determination of the K value

The K values are measured according to Fikentscher, Cellulosechemie, vol. 13, pp. 58 to 64 (1932) at 25 ° C in aqueous / ethanolic or ethanolic solution and represent a measure of the molecular weight. The aqueous / ethanolic or ethanolic solution the polymer contains 1 g of polymer in 100 ml of solution. In the event that the polymers are in the form of aqueous dispersions, appropriate amounts of the dispersion are made up to 100 ml with ethanol, depending on the polymer content of the dispersion, so that the concentration of 1 g of polymer in 100 ml of solution is produced. The K value is measured in a Micro Ubbelohde capillary type M Ic from Schott.

Calculation of the K value with correction of the mixture for water in ethanol The factors listed below in the equation for the correction of the mixture refer exclusively to this type of capillary at a measuring temperature of 25 ° C.

Calculation of K-value:

K = k * 1000; z = η _re ι

Relative viscosity: ηrel = (t..sg - HC | _sg) / (ti_ - HC | _M)

Calculation of the mixture correction:

Mixtures of water in ethanol show non-proportional changes in the viscosity of the solvent mixture in relation to the proportion of water.

Due to the nature of the sample (aqueous dispersion of a polymer), water is introduced into the ethanolic sample solution through the sample weight. This amount of water is included in the running time of the solvent by the correction of the mixture, so that the relative viscosity is corrected in accordance with the addition of water.

Running time solvent mixture:

Time Correction:

t _M = - 7.486100e-5 * c _w ⁴ + 3.785884 E-3 * Cw ³ - 8.063441 E-2 * c _w ² + 1, 999207 * Cw + 2.959258E-2

Solvent content water:

Cw = c / FG / 100 * (1 - FG / 100)

c concentration of the measuring solution [g / 100ml] c concentration of water in the measuring solution [g / 100ml]

Curl retention:

The damp strand of hair is squeezed out between filter paper, dipped three times into the polymer solution (formulation without propellant gas), wiped off with your fingers in between and squeezed off again between filter paper. Then the hair is wrapped around a teflon rod and fastened with filter paper and a rubber ring. The strands of hair are then dried in a warming cabinet at 70 to 80 ° C. for about 90 minutes. After cooling to room temperature, the curls are stripped off while maintaining the shape and hung on a specially made frame and the curl length (L ₀ ) is measured on the attached scale in cm.

To determine a curl retention value, 5 locks of hair are to be used. The curls are hanging in a climate chamber with 20 ° C and 75% or 90% rel. Humidity set. After 5 hours the length (Lt) is read.

The curl retention is calculated as follows: L - Lt

Curl retention in% = * 100 L - L ₀

L = length of the hair (15.5 cm) L ₀ = length of the lock of hair after drying L _t = length of the lock of hair after climatic treatment The mean value from the 5 individual measurements after 5 h at 20 ° C. and 75% or 90% rel. Moisture specified.

Bending strength:

The dry, weighed strands are immersed three times in demineralized water, stripped, pressed between filter paper and weighed. The strands are then dipped three times into the polymer solution to be tested (formulation without propellant gas), stripped off with the fingers when pulled out and also pressed and weighed between filter paper. The strand is then shaped by hand so that the cross section is as round as possible. The strand is hung free to dry with a clamp in a climate room (21 ° C and 65% rel. Humidity) overnight. The tests are carried out in a climate room at 21 ° C and 65% rel. Air humidity carried out using a tension / pressure tester (type Easytest 86 802, Frank). The strand of hair is placed symmetrically on two cylindrical rollers (diameter 4 mm, distance 90 mm) of the sample holder. In the middle, the strand is then bent 40 mm from above with a rounded punch (breaking the polymer film). The force required for this is measured with a load cell (50 N or 10 N) and specified in Newtons. Each polymer solution is tested on 5 different strands of hair.

As a result, the average of the 5 individual measurements is used.

The determinations of the K value, the pH value, the curl retention and the flexural strength were carried out for the formulations listed in Table 2.
